Civil Engineering

Using the absolute volume method, a colleague started a mixdesign for a simple concrete foundation in a mild climate and gotthrough Step 5 and has asked you to finish the work. They havealready determined the mix needs:
• a w/c ratio of 0.45
• a 2” slump
• 1830 lb of gravel in the oven dry conditions,
• and 3.5% air provided by air entrainer.
The available gravel (coarse aggregate) is subangular with a NMSA =3⁄4”. It has a specific gravity, Gs = 2.7, with a moisture contentof 1.8% and an Absorption of 2.2%. The available sand (fineaggregate) has a specific gravity, Gs =2.45, with a moisturecontent of 3.8% and an absorption of 2.4%. Gs of cement = 3.15.

For each cubic yard of concrete for this mix, determine:
• the total weight of water, cement, moist sand, and moist gravelrequired. Don’t worry about the amount of
air entrainer product in fluid ounces.
• Summarize the total mix design (neglecting the required fluidounces of air entrainer)
